DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin rain basin.

[0002]

[Prior art and its problems] In general, drainage facilities called masashi include sewage and rainwater, and of these,
Rainwater Masumi collects rainwater that falls on road surfaces, residential lands, vacant lots, etc.
Equipment for containing, checking and cleaning rainwater pipes, requires a bottom with a depth of 15 cm or more at the bottom to prevent earth and sand from flowing into the downstream sewer. I have to. In addition, when installing this rainwater trough on a residential land or the like and collecting rainwater, it is necessary to attach a grate lid.

[0003] Since most of conventional rain water basins are made of concrete, the appearance of synthetic resin rain water basins has been demanded due to low cost, compactness, and connectivity with PVC rain water pipes. For this reason, for example, a bucket-shaped polypropylene rainwater basin with a check tube receptacle and a spout for outflow / incoming rainwater pipes has been partially implemented, and a proposal to improve this polypropylene rainwater basin has been made. Has also been made.

[0004] For example, Japanese Utility Model Laid-Open No. 5-22679 discloses a PVC main body, a check tube capable of cutting a tube, an integrally connected lower portion of the check tube, and successively increasing the diameter downward. In other words, it has been proposed that a rainwater pool made of PVC is constructed, which consists of a truncated conical bottomed mud sump, and an outflow / inlet drilled in this mud sump and a rainwater pipe inserted into each of these entrances and connected. .

[0005] However, in such a PVC rainwater basin proposed as described above, in order to adjust the position of the buried depth of the shallow type or the deep type, the check tube can be cut and adjusted, but the depth of the mud sump portion can be adjusted. If you try to adjust it, the shape of the mud reservoir is frustoconical and the bottom is covered with a bottom cap, so if you change the depth of the mud reservoir, the bottom cap will have a diameter corresponding to that In addition, there is a problem that cleaning is troublesome because the shape of the mud reservoir is a truncated cone.

Of course, in the case of a bucket-shaped polypropylene rainwater having the above-mentioned check tube port and the outlet for the outflow and inflow rainwater pipes, if the depth of the mud sump is to be changed, the whole will be changed. There was a problem that it had to be replaced.

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the above-mentioned problems, and the gist of the present invention is to provide an inspection in which an inspection tube which is upwardly covered and which can be cut and cut is bonded and bonded. In the rainwater masu body of the synthetic resin small-diameter sewage type provided with a plurality of rainwater tube reception holes for bonding the rainwater pipe made of PVC in a horizontal direction, the rainwater masu body downward, A connecting cylinder of the largest possible diameter opened in the main body is extended by integral molding, and a bucket-shaped injection-molded bottomed mud reservoir having a different depth is selected for the connecting cylinder, and one-touch operation is performed. A synthetic resin rainwater trough, which is detachably connectable to a type and has a sediment trapping basket stored in the bottomed mud reservoir.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to an embodiment shown in the accompanying drawings. FIG. 1 is a sectional view of a first embodiment of the present invention, FIG. 2 is an enlarged detailed view of a main part of FIG. 1, and FIG. 3 is a partial sectional view of a second embodiment.

The synthetic resin rainwater basin according to the first and second embodiments of the present invention is a commonly used small-diameter PVC sewage system (a sewage system in which various pipe fittings are provided with an upward-looking check tube).
It is mainly composed of a PVC main body having a socket capable of TS joining (also called DV joint) as described above, and is compact and inexpensive, and is suitable for rainwater installed in residential land.

A first embodiment will be described. In FIG. 1, 1
Is the main body of a PVC injection molded product.
A 200 mmφ inspection tube socket 2 is provided, and 7
Rainwater pipe receptacles 3 and 4 on the inflow side and the outflow side of 5 to 100 mmφ are provided.

[0011] These receiving ports 2, 3 and 4 are made of a standard JIS.
Although a standard TS connection port may be used, it is configured as an adhesive connection port suitable for a compact synthetic resin rainwater as shown in FIG. 2 and described later. The rainwater pipe receptacles 3 and 4 are not limited to the straight type shown in the figure, but are 90L type orthogonally viewed in plan view, 45L type bent at 45 ° in plan view, and one or two receptacles orthogonally orthogonal to the straight type. And any type employed in small-diameter sewage masu, such as for a starting point. Therefore, in the main body 1, the types of the rainwater pipe receptacles 3, 4 can be diversified to provide an assortment of products, and if the standard type mud storage section 10 described later is shared, the cost can be reduced as a whole. In addition, since the strength of the connection with the rainwater pipe can be maintained, it is convenient for the diversified rainwater of buried residential land.

The main body 1 has a main body 1 facing downward.
The outer diameter D of the circular body 5 is extended as it is to make the spout length,
This is configured as a connecting cylinder 6. The connection tube 6 is increasingly open in the main body 1. Therefore, since the diameter of the connection cylinder 6 is made as large as possible, the capacity of the mud reservoir can be increased while using a small-diameter rainwater. In addition, the outer diameter D of the connecting tube 6 is particularly adapted to the outer diameter of a commercially available PVC pipe (for example, a nominal diameter of 150 to 200 mmφ). In addition, if this PVC pipe is provided with a hole, the strainer-type rainwater can be immediately permeated.

A reduced-diameter ring 7 is integrally provided at an opening in the main body of the connecting cylinder 6.
The opening flange of the earth and sand trapping basket 8 having a drain hole at the bottom can be loosely fitted. Of course, the basket 8 may be suspended by hooking the opening flange of the sediment catching basket 8. The basket 8 is provided with a lowering hand 8a which is always erected. An arc-shaped claw 9 is provided around the middle of the inner circumference of the connecting cylinder 6.

The connection cylinder 6 is provided with a bucket-shaped bottomed mud reservoir 10 which is detachably provided in a one-touch manner. That is, the bottomed mud reservoir 10 is a PVC injection-molded product, and a stopper stepped portion 12 with which the lower end of the connection tube 6 comes into contact is formed above the middle of the outer periphery of the bucket body 11. . Above the stopper step portion 12, a concave portion into which the arc-shaped claw 9 is elastically deformed and fitted, and an O-ring 13
Is formed therein. The bottomed mud sump 10 is configured as a standard type with a mud sump depth of about 160 mm, but with a mud sump depth of about 300 mm or about 500 mm.
Some of them are also provided. Of course, if the arc-shaped claw 9 is provided on the outer periphery of the bucket body 11, these two concave portions will be provided on the inner periphery of the connection tube 6.

Next, a description will be given of the structure of the receptacle S for the check tube and the rainwater pipe provided on the main body 1. 2 showing a receptacle for rainwater pipes, masu body 1 a receptacle length L of the receiving S provided on the first adhesive length S ₁ and second adhesive length S ₂ and the guide portion length S ₃ And S ₁ = 1/2 to 2 / 3L. Further, the surface taper of the _second bonding length S2 is set to the first taper.
Is the larger than the surface taper of the adhesive length S ₁ of the. In particular, S
₁ side taper (e.g., 1 ° when the nominal diameter 100 mm 8'45 °) and _{S 2} surface tapered (e.g., nominal diameter 1
In the case of 00mmφ, 2 ゜ 17'26 ”) is JIS standard T
It is larger than the surface taper of the S junction (for example, 0 ゜ 34 ″ in the case of a nominal diameter of 100 mmφ).

Therefore, in this synthetic resin rainwater trough, the receiving port length L (for example, 30 mm in the case of a nominal diameter of 100 mmφ) is maintained while maintaining the adhesive strength in order to prevent falling.
Can be shortened to the length of the JIS standard PVC pipe TS joining port (for example, 50 mm for a nominal diameter of 100 mmφ).

Therefore, when the receiving port S is used as the rainwater pipe receiving ports 3 and 4, space-saving piping can be achieved, and the pipe shaft can have a slight deflection angle θ. Becomes easier.

Further, when such a receiving port S is used for the check pipe receiving port 2, the rainwater mist installed at the uppermost stream in the house can also be used.
The specified minimum soil cover depth from the ground can be ensured.

Next, the operation of the first embodiment will be described. Select a bottomed mud reservoir 10 with a mud depth corresponding to the buried place such as a residential land or a boundary between a residential land and a public road, and a main body 1 having a rainwater pipe receiving port adapted to a pipe of a PVC rainwater pipe 15. Choose and fit both. And the basket 8 for sediment capture
Is stored and placed in the bottomed mud storage unit 10. On the other hand, the inspection cylinder 14 adjusted to the burying depth is bonded to the inspection cylinder receptacle 2 by adhesive bonding.

After the synthetic resin rainwater basin as described above is installed, for example, between the synthetic resin rainwater infiltration cells, the rainwater pipe (or perforated permeation pipe) 15 is connected to the rainwater pipe receiving port 3, 4 and adhesively bonded. At this time, if the rainwater basin is also used for collecting water, the lattice lid 16 is attached to the inspection tube 14. When sediment accumulates in the sediment catching basket 8 with the rainwater basin thus installed, the basket 8 is taken out and removed. The lattice lid 16 uses a small-diameter sewage lid as it is, only by providing a large number of through holes in the sewage lid.

Next, a second embodiment will be described. FIG.
In the second embodiment, the mussel body 1 of the second embodiment is a confluence type provided with three or more rainwater pipe receptacles, and the eccentric different diameter pipes are provided in these rainwater pipe receptacles 3, 4, and 4 '. A joint 17 is attached to each, and a rainwater pipe is adhesively bonded thereto. Therefore, the rainwater basin of the second embodiment is preferably installed in a place where a large amount of sediment flows, since the capacity of the mud reservoir 10 is increased.

In the above embodiment, the connecting cylinder 6 is described as a spigot. However, the outer diameter of the circular cylinder 5 may be slightly reduced to constitute a receiving port. However, the basket 8 may not necessarily be used, but may be simply stored. In addition, the arc-shaped claw 9 and the concave portion are described as being fitted by resin elastic deformation. Connection may be used).

Further, instead of the bottomed mud reservoir 10 fitted to the connection tube 6 of the present invention, a synthetic resin infiltration part having a slit or the like may be fitted to the main body 1 more or less. By doing so, it is possible to configure the rainwater permeation immediately.

[0024]

According to the present invention, a downwardly facing connecting cylinder is extended from the main body by integral molding.
A variety of injection-molded bottomed mud reservoirs with different mud reservoir depths can be connected to this connection cylinder in a one-touch manner so that it can be attached and removed in a single touch. A rainwater masque with an appropriate capacity can be formed, and a rainwater squid that is inexpensive and suitable for a construction site can be provided. A downward-facing connection cylinder is extended integrally with the main body, which has various rainwater pipe receptacles, and a standard injection-molded mud reservoir can be detachably connected to this connection cylinder in a one-touch manner. Despite being a mud reservoir, it can provide rainwater according to the piping condition of the rainwater pipe. The rainwater masu body is made of a synthetic resin small-diameter sewage type, so low cost, compactness, easy handling, and easy connection with PVC pipes are maintained as they are, further encouraging the construction of synthetic resin rainwater masu. Can contribute. Since the main body and the mud reservoir are separately molded, the injection molding die is small and inexpensive, and the production cost can be reduced. In particular, since the main body is similar in size and shape to the small-diameter sewage body, an injection molding machine for small-diameter sewage basin, which is widely used, can be used as it is.
